Summary: In general, I've been disappointed by my ReadyNAS. While it may have been a nice device ten years ago, it unfortunately shows its age in its software. For a home user with modest experience with network storage, the ReadyNAS Ultra 2 seems like a typical device.
Summary: The first problem I had with this device is that there were no hard drive mounting screws, and the drives are too close together to use a standard screw (the screw heads bump into each other because the drive slots are too close together). So I ended up using the screws you hold lightplates on with.
Summary: I must have received a lemon. Performance copying files was OK (45 - 75 MB/s), but Time Machine performance crawled between 216 kb - 2.9 MB/s. Also, it came with two Seagate ST2000DL003 installed. Less than 48 hours after first turning this on, one of the drives failed SMART tests.
